Abstract

The invention provides an LED street lamp system for solar power generation with high-voltage direct current centralized power supply, which includes an LED single lamp module, a DC bus bar, an AC bus bar, solar grid-connected inverter equipment, and high-voltage direct current centralized power supply equipment; the LED single lamp module includes a solar battery panel, LED street lamp and intelligent single-lamp controller; the solar panel generates power through the intelligent single-lamp controller, DC bus and solar inverter grid-connected equipment; the high-voltage DC equipment provides high-voltage DC power for the LED street lamp through the DC bus support. The street lamp system of the present invention can not only generate electricity, but also the solar panel power generation and the high-voltage DC power supply share a two-core cable, which reduces the investment cost of the street lamp system; in addition, the street lamp system of the present invention is powered by high-voltage DC , to ensure the lighting rate.

Description

technical field [0001] The invention relates to the field of street lamp design, in particular to an LED street lamp system for solar power generation high voltage direct current centralized power supply. Background technique [0002] The current LED street lamp system adopts the technology of three-phase four-wire AC power supply, single lamp and single power supply. Most street lamp cables use 5-core cables, which account for more than 30% of the investment cost of street lamp systems. [0003] However, the current solar street light system is limited by expensive batteries with limited lifespan, and the application cost is high; at the same time, in order to ensure the lighting rate in rainy weather, the capacity of solar panels and batteries are equipped with high capacity, and the resource utilization rate is usually low, resulting in It is a big waste, and it is still difficult to guarantee the lighting rate in extreme weather. [0004] The current street lamp depart...
